Hi Darren,

Agreed.  It is having a choice to fit your particular needs.

In my experience (I am by no means a programming expert), the
"writing" of the code is far easier than the "maintaining" of the code.
The extra time one spends on the initial write to make it 8nderstandable,
save me 10 to 20 fold down the road.  I am a YUUUGE fan of Top Down.

In P5, I spend great amount of time naming and commending the
sub variables to make them understandable.  I even use the ($$)
business to make sure I call them correctly.  In P6, the sub variable
naming serves both the name and the comment.  Easy to figure
out at a glance.

There's https://github.com/fglock/Perlito but it's incomplete, and may not
generate idiomatic or too performant code. I recall trying to use it to compile
Perl 5 to JavaScript and after I went to a lot of effort in either fixing
Perlito itself or adapting my code for it to be more compatible with it, it was
executed slower by Node.js than the Perl 5 original.

Todd, I'm with you. I have lots of p5 code I would like to switch to p6 and
see a translator useful to save the grunt work of initial conversion.  I
much prefer cleaning up workable code than manually starting from scratch.

Just my two cents.

Best regards,

In principle there is nothing wrong with @_ at least from the perspective that 
it is quite useful to be able to have a single variable or keyword to represent 
the entire argument list as a single value.  Logically, a single value is what 
an entire argument list is anyway, with individual arguments being components of 
that. -- Darren Duncan

it was the Perl 6 since each page is alphabetical by language!

Hi,

What's the use case for converting Perl 5 to Perl 6 automatically?

If you want to use Perl 5 code from within your Perl 6 code, you can do
that through Inline::Perl5.

But automatic translation (if it works at all) typically doesn't produce
good or idiomatic code, so you should try to stay away from it.

Cheers,
Moritz
